10,000 Kilometres to Metres per Second: A Comprehensive Guide

Overview

This article provides a comprehensive guide to converting kilometres (km) to metres per second (m/s). It covers the conversion formula, applications, examples, and a step-by-step approach for making the conversion accurately.

Conversion Formula

The conversion formula for kilometres to metres per second is:

1 km = 1,000 m
1 s = 60 min
1 min = 60 s

Therefore, 1 km/s = 1,000 m/60 s = 16.667 m/s

Applications

The conversion of kilometres to metres per second has numerous applications in various fields, including:

kilometres to metres per second

Physics: Calculating speed and velocity
Engineering: Designing and analyzing mechanical systems
Astronomy: Measuring the speed of celestial bodies
Transportation: Converting speed limits and vehicle speeds

Examples

Here are some common examples of the conversion:

A car traveling at 120 km/h is moving at 33.33 m/s
A plane flying at 900 km/h is moving at 250 m/s
A satellite orbiting Earth at 28,000 km/h is moving at 7,778 m/s

Step-by-Step Conversion Approach

To convert kilometres to metres per second, follow these steps:

Convert kilometres to metres: Multiply the value in kilometres by 1,000.
Convert seconds to hours: Multiply the value in seconds by 1/60/60.
Divide kilometres by hours: Divide the value in metres by the value in hours to get the speed in metres per second.

Table 2: Applications in Physics

Application	Formula	Example
Velocity	v = d/t	A car traveling 200 km in 2 hours has a velocity of 200/2 = 100 km/h = 27.78 m/s
Acceleration	a = Δv/Δt	A rocket accelerating from 0 to 300 km/h in 10 seconds has an acceleration of 300/10 = 30 km/h/s = 8.33 m/s²
Impulse	FΔt = Δp	A force of 100 N applied for 2 seconds produces an impulse of 100 x 2 = 200 Ns = 13.89 kg m/s

Table 3: Applications in Engineering

Application	Formula	Example
Gear Ratio	r = N₁/N₂	A gear with 20 teeth and a pinion with 10 teeth has a gear ratio of 20/10 = 2
Angular Velocity	ω = 2πf	A rotating shaft with a frequency of 10 Hz has an angular velocity of 2π * 10 = 20π rad/s
Moment of Inertia	I = mR²	A flywheel with a mass of 100 kg and a radius of 0.5 m has a moment of inertia of 100 * 0.5² = 25 kg m²

Table 4: Applications in Transportation

Application	Formula	Example
Speed Limit	v = d/t	A speed limit of 100 km/h is equivalent to 27.78 m/s
Vehicle Speed	v = ωr	A wheel with a radius of 0.5 m rotating at 200 rpm has a speed of 2π * 200 * 0.5 = 628.32 m/s
Fuel Consumption	fc = d/v	A car that travels 200 km on 10 litres of fuel has a fuel consumption of 200/10 = 20 km/l = 5.56 m/s / l
